WATERING DEVICE FOR GRINDSTON'ES.

Application filed May 28, 1915.

To all whom it may concern:

Be it known that I, Josnrn H. Kine, a

citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Watering Devices for Grindstones, of'which the follow-- ing is a specification.

The present invention comprises a device for positively ejecting a cooling medium, such for instance as water, directly onto the periphery of an emery or other grinding wheel; the objects thereof being to minimize the quantity of fiuid used'and to provide for the uniform distribution of the same about the entire wearing surface of the wheel.

Various other objects and advantages will i become apparent during the continuance of the following description.

The above and other objects which will become apparent, are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification and then more specifically pointed out in the appended claims.

In the accompanying drawings wherein like characters designate like parts throughout the several views; Figure 1 is a side elevation of an ordinary grind stone illustrating my invention in conjunction therewith. Fig. 2 is a vertical sectional view of the supporting frame illustrating my invention partly in section and partly in elevation. Fig. 3 is a fragmentary view of an improved force pump which is employed in connection with my invention. Fig. 4 1s a detail view illustrating means to actuate the force pump.

In order to facilitate a concise illustration of my invention and a complete description thereof, I have shown in the drawings, an ordinary grind stone and supporting means therefor. However it 1s to be understood that my invention is not particularly limited to use in connection with this device and that the same may be advantageously employed in connection with other forms if it is so desired.

In thedrawings the numeral 10 des gnates a series of upright standards which are connected adjacent their upper ends by Specification of Letters Patent.

tain the same in a rigid position during the operation of the grind stone.

bupporting bearings lt'are fixed to the respective longitudinal members 12 at suitable points and are designed to support the respective shaft sections 15 and 16. The

shaft section 15 carried an enlarged member 17 which is interiorly' screw threaded in order to receive the exteriorly screw threaded shank 18 of the other shaft section. Operating handles 19 and 20 are fixed to the outer end of the shaft sections 15 and 16 respectively and provide means for rotating the same manually or by connection with suitable propelling mechanism.

In conventional devices. of this-type, the grmd stone 21 is usually positioned on the shaft section 15 at a point adjacent the enlargement 17. However in the present device the grind stone 21 isspaced some dis tance from the said enlargement in order to permit an eccentric 22 to be positionedtherebetween.

'The eccentric 22 is provided with a circumferential groove 23 within which operates an annular collar 24. The collar 24: is in turn provided with a depending rod 25 which is adapted to have connection with a suitable plunger head which will be presently described. It will now be noted that the rev'oluble movement of the respective shaft sections 15 and 16 will impart a reciprocatory movement to the rod 25 such as may be utilized for operating a suitable force pump.

A .water box 26 is employed and is provided with a series of adjustably attached suspending irons 27. By reason of the fact that the lI'OIlS 27 are provided with a series of openings 28, it will be understood that the water box may be adjusted to different.

positions thereon in accordance with the existing conditions.

When the suspending irons are may be employed for the purpose of securely attaching the same to the members 12.

"A pump cylinder 30 is provided and adapted to be arranged at a suitable point within the water box. In order to efficiently support the pump cylinder and allow a slight oscillatory movement thereof, shaft sections 31 and. 32 are carried on the fixed collar 33 and are journaled through the respective sides of the water box as shown in Fig. 2. Suitable fastening means such as indicated by the numerals 34 and 35 may be employed for the purpose of retaining the shaft sections 31 and 32 and thus preventing lateral movement of the pump cylinder with respect to the water box. Other bearings 36 may be also employed in conjunction with the shaft sections 31 and 32 for conveniently supporting.

the same in connection with the sides of the water box and to allow slight rotation thereof in accordance with the amplitude of oscillation of the pump cylinder.

The lower end of the rod 25 projects into the pump cylinder and is attached to a piston head 37, the latter carrying a suitable flap valve 38 which operates in the mannertrolling the ingress of fluid from the water box. If it is desired a valve seat 42 may be arranged within the member 40 in order to cooperate with the valve 41 and provide for the positive seating of the latter simultaneously with the downward movement of the plunger head. However as this valve seat forms no principal part of the present invention, it is to be understood that other different forms may be substituted if occasion requires. In order to convey the fluid from the pump cylinder and eject the same directly onto the periphery of'the grind stone 21, a jet pipe 43 is employed, one end thereof being secured to the pump cylinder at a point adjacent the upper end thereof, while its free end is arranged in proximity to the lowermost point of the periphery of the grind stone.

The operation of the force pump is substantially as follows :.Assuming that the plunger head 37 is in its lowermost position, the alve 41. will be closed. Now as the plunger head moves upwardly in the pump cylinder the valve 41 is unseated by the action of the partial vacuum which is formed within the cylinder and will allow fluid from the water box to be sucked into the cylinder 30. When the plunger head 37 reaches its uppermost position (which. is above the point of connection with the jet pipe 43) the valve l1 will be automatically seated and the valve 38 in the plunger head unseated so as to allow the fluid in the pump cylinder to pass through the plunger head during the downward movement of the same. Now when the plunger head again moves toward the upper end of the pump cylinder other fluid will be brought into the lower end of the cylinder and the fluid in the cylinder above the plunger headwill be forced outward through the, jet 4:3 and ejected directly onto the periphery of the grind stone.

It is to be understood that the stroke of the rod 25 and the respective plunger head is proportionate to the size of the eccentric 22 in order that the same may complete a stroke simultaneous with one complete revolution of the eccentric. Thus when the grind stone is run at a high rate of speed, the cooling medium will be ejected .thereto in proportion and as the speed of the grind stone decreases, less water will be used.

Fromthe foregoing it is believed that the advantages and novel features of my present invention will be readily recognized, however attention is again directed to the simple construction and obvious durability of the device.

find that form referred to herein as the most practical and preferred embodiment is the most eflicient, but realizing that certain conditions will necessarily vary in concurrence withthe adoption of my device, I desire to emphasize the fact that various minor changes in the details of construction and in the proportion of parts may be resorted to when required without sacrificing any of the advantages of my invention as defined in the appended claims.

Having thus .fully described my invention, what I claim as new and desire to secure by Letters Patents is:

1. The combination withagrinding wheel and supporting apparatus therefor, of a water box, means having connection with said supporting apparatus to adjustably support said water box, pump means swingingly mounted in said water box and arportionate to the speed of rotation of said.

grinding wheel.

2. In combination with a grinding wheel,

low said grinding wheel and in vertical alinement therewith, a pump cylinder, means swingingly supporting said pump cyl close proximity to the periphery thereof, an'

eccentric mounted to rotate with said grinding wheel, a piston in said pump cylinder, and a ring on the upper end of said piston having connection with said eccentric as and for the'p'urpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.
